TO ALL WHOM IT MAY CONCERN:

4Be it known that I, OM. POND, of Independence, `in the county of Buchanan, and State vof Iowa, have invented certain new and useful Improvements in aCombined Seeding-Machine and' Cultivator; and Ido hereby declare that the following is a full and' complete description of the construction and operation of. the saine, reference being had to the accompanying drawings, mak-ing a part of this specification, in which-,- 7

Figure 1 is an end view of the seeder.

Figure 2 is a view of the rear side. Figure 3 is a top View. Figure 4 is a detached section.

Like letters of reference refer .to like parts in the views. v n On the wheels A, fig. 3, is mounted the axle-tree B, to which is attached a frame, O; in said frame is placed and secured a seed-box, D, the bottom of which is composed of 4two parts, -E F, iig. 4. Part E is fixed rigidly to the box, whereas part F is adjustable, so that it can be moved back from E, more or less, as indicated by the dotted linesV a, thereby making a longitudinal opening, I), along the bottom, of greater or less capacity, for a purpose hereafter shown. G vis a slide by which the opening referred to may be closed, and which is operated by Vthe lever II. At the-bottom ofthe box is jonijnallethin the Vends of the same, a square iluted feed-roller, I, figs. 3 and 4, which is made to revolve by a belt, J, running from the pulley K to L, the pulley K being attached to and driven by the wheel A. To the under side o'f the frame C is attached a shaft, M, iig. 2, from which proceed the arms N. To the extreme ends of said arms are xed the cultivator-teeth O, which, when the machine is in use, are in the position shown in tig. 1'. These teeth may be lifted entirely from the groundv by the adjustable rail I?, iig. 3, extending across the machine `immediately under the arms, said rail Abeingattached to a lever, A', by a cord, c, and by which it and the cultivators are raised upward by pulling the lever back to the position indicated by the dotted lines d, iig. 1, and is retained in this position by slipping the lever into .a notch eut into the side of the frame B.. C', iig. 3, is a check-bar hinged to the axle-tree, which, on being' let down as indicated by the dotted lines a', fig. 2, reaches to the top of the arms N, and thereby prevents'the arms and cultivator from bcingrthrown up out of the ground while the machine is in operation; hence the teeth are held firmly into the ground, and` at any desired depth, by raising or lowering the check more or less, as is necessary.

The practical use of this machine is for sowing grain, grass-seeds, 86e., broadcast, and is performed as follows:

The seed is thrown into the box, the bottom of which is then opened more or less, according to the kind of seed, -by means of the adjusting-screws D', iig. 1, or in order to gauge the amount to'be sown to the` acre. The operator takes his place upon the seat E', and on starting moves the slide G, by means ofthe lever-H, from the adjusted opening in the bottom ci' the seed-box. As the machine moves forward, dropping the seed, it is raked Ain by the cultivators O, to apgrcuter or lessdepth, according to the adjustment of theclieck-bar referred to.

The bottom of the box is made slightly dishing, by which, and by means ofthe roller I, all the seed is made to run out, so that there isno lodgment of the grain in the corners ofthe box, and at the same time sec'uresa 'uniformity in the discharge of seed to the ground', so that'the sowing is evenly and regularly performed, withmuch less labor, and more expeditiouslythan by hand.`

What I claim asmy improvement, and desire to secure byLettors Patent, is-

1. The seed-box D, provided with an adjustable bottom, EF, and slide G, in combination with the flnted feedroller I, for the purpose and in the manner as set forth.

2. The cnltivators O, adjusting-bar I), check-bar C', as constructed and arranged to operatc'in relation to the seed-box D, for the purpose substantially as described.

O. M. POND.
